X1Y3 Battery Drain & Fingerprint Reader Issue on Standby

I have the X1Y3 recently bought directly from Lenovo and am exclusively running Windows 10 Professional.

 

I have noticed when I put the computer on standby:

a) the battery drains quite quickly - approximately 70% over about 36 hours

b) on occasion (maybe 10% of the time), the fingerprint reader does not activate when returning from standby. It works fine when booting fresh.

 

I have no USB devices plugged in when I leave the computer on standby.

The Thinkpad light pulsates in and out to confirm it is in standby.

When the computer is fully shutdown with nothing connected to it, I do notice about a 5-10% battery loss per day.

 

I would try removing the battery but I can't in this model without probably voiding warranty.

 

Any idea how to fix this?

 

Thanks

I do not own a X1Y3 (yet), but I had similiar problems on my T440s with massive battery drain when shutdown.
Disabling the USB-Charging in the Vantage app helped a lot, you could give it a try if it is turned on.

Re: X1Y3 Battery Drain & Fingerprint Reader Issue on Standby

^Thanks for the suggestion!

I went ahead and turned off USB battery charging in the Lenovo Vantage app

I've also made sure the bios is set to disable power to USB upon sleep/shutdown

I've confirmed that my USB mouse that's plugged in doesn't light up anymore when the laptop is in sleep mode.

 

I've noticed that in about 12 hours, I've lost around 13% of battery while on sleep.

I've noticed significantly less reduction in battery life with my old x200t.

 

Not sure what else to do to diagnose this.
